GREASE-CUP.

Specification of Letters Patent.

Application filed March 26, 1913.

Patented Feb. 3, 191%. Serial No. 756,987.

To all whom it may concern Be it known that I, NORMAN W. CUM- MINS, a citizen of the United States, residing in the city of Bridgeport, county of Fairfield, State of Connecticut, have invented certain new and useful Improvements in Grease-Cups; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain new and useful improvements in grease cups, and pertains more particularly to the means in a force feed cup for preventing retrograde movement of the cap that constitutes the feeding element.

The primary object of the invention is to generally improve, simplify and reduce the cost of manufacture of the means for preventing retrograde movement of the cap.

In the drawings :Figure 1, is a vertical sectional view of the invention; Fig. 2, is a section on the line 22 of Fig. 1; Fig. 3, is a section on the line 3--3 of Fig. 1; Fig. 4, is a section on the line 4:4 of Fig. 1; Fig. 5, is a top plan view of the disk that retains the spring of the post in position; Fig. 6, is a detail perspective view of the post or stem; and Fig. 7, is a top plan view of a modified form of spider.

The body 1 is preferably of hexagonal cross-section, and has a reduced exteriorly threaded lower end 2 that is provided with an outlet 3. The upper end of the body is provided with an outwardly extending annular flange ff which is engaged by an inwardly extending flange 5 formed at the base end of a reinforcing member 6, the flange 5 having a hexagonal opening which conformably receives the hexagonal body and is thereby held against rotation. A spider 7 which as shown in Fig. 3 has four radially extending arms, or which as shown in Fig. 7, may have but two radial extending arms, has the outer ends of said arms seating on the upper face of the flange 4. The upper or free end portion of the reinforcing member 6 is forced inwardly to seat on top of the spiderarms as indicated at 8, whereby said inwardly forced portion constitutes a flange which combines with the flange 5 to Clamp the spider on to the body. The peripheral portion of the reinforcing member is threaded to engage with the threads formed on the interior of a cap 9.

The cap 9 is closed at its outer end and is provided with an annular groove 10 which is undercut or is of greater diameter than the diameter of the threaded portion of the cap, in order to receive an inclined flange 11 that is formed at the periphery of a thin sheet metal disk 12. The disk 12 is provided with a teat 13, which is struck out therefrom so as to extend in close proximity to the closed end of the cap, while the center of the disk is provided with a perforation 1 1 to rotatably receive the head 15 of a post 16, the latter being square or angular in crosssection and being projected at its lower end through an aperture 17 of similar configuration, that is formed in the center of the spider 7, whereby the post 16 is held against rotary movement by the spider. The material of the disk 12 that surrounds the aperture 14: is preferably depressed in order to provide a seat for the head 15 of the post 16. A U-shaped spring 18 has its legs engaging over the upper squared portion 19 of the post 16 that projects above the head 15 of the latter, and has its closed end engaging with the teat 13.

After the stem or post 16 has been passed through the opening 14:, the spring 18 is placed on the post and the teat as shown in Figs. 1 and 2, after which the disk 12 is forced, by a suitable tool, into the groove 10 of the cap, which causes the flange 11 to expand into said groove with the result that the spring is held between the closed end of the cap and the disk in the position shown. hen the cap is rotated on the body 1 at every quarter revolution of the cap the corners of the head 19 in spreading the legs of the spring 18, and in the return of the latter to the position shown in Fig. 2, will communicate to the operator, by the sense of feel, andthe temporary arresting of the cap in its rotation, the fact the cap has been revolved through an arc of ninety degrees, which enables the operator to determine the amount of movement of the cap in order to force the proper amount of grease through the outlet 3. The spring holds the cap against accidental movement, While still allowing rotation thereof when manual force is applied thereto.

I Vhat is claimed is:

1. In a grease cup, a body having an outwardly extending flange at one end thereof, a spider engaged with the top face of the flange, a reinforcing member having an inwardly extending base flange and a top flange which latter extends inwardly to engage the top face of the spider to clamp the latter on top of the body flange, said spider having a central angular opening, a cap threaded over the reinforcing member and having spring means on its interior, and a post engaged at one end with said spring means and having its other end extended through the angular opening of the spider to be held from rotation by the latter.

2. In a grease cup, a body, a stem nonrotatably connected to the body, a cap threaded into engagement with the body, a disk having an opening to receive the stem, and having a projection which extends toward the closed end of the cap, and a U-shaped spring the closed end of which engages over the projection and the free ends of which engage with the stem.

3. In combination with a body having an outwardly extending flange at one end thereof, an element seating on said flange, a reinforcing member having inwardly extending base and top flanges which engage the body flange and said element respectively, a cap movable relative to the body, and means between the cap and element whereby the cap may be rotated relative to the body but is held against accidental rotation.

4C. In combination with a body and a stem non-rotatably connected to the body, a cap movable relative to the body and having an interior annular undercut groove, a thin sheet metal disk having an inclined peripheral flange which is engaged in said groove, said stem at one end extending through an aperture provided therefor in said disk, said disk having an integral teat displaced therefrom and extending toward the cap, and a U- shaped spring having its closed end engaged over said teat and having its free ends engaging the said end of the stem.

5. In combination with a body and a stem non-rotatably connected to the body, a cap movable relative to the body and having an interior annular undercut groove, a thin sheet metal disk having an inclined peripheral flange which is engaged in said groove, said stem at one end extending through an aperture provided therefor in said disk, the portions of the disk immediately surrounding said aperture thereof being depressed to form a seat, a head on the stem disposed in said seat, a teat on the disk Which terminates adjacent the cap top, and a spring engaged with the teat and said end of the stem.

In testimony whereof I aflix my signature in presence of two witnesses.
